Abstract
An electrochemical cell degradation monitoring method. The method includes applying first and second bias potentials to an electrode of an electrochemical cell during an operating state thereof. The method further includes measuring impedance spectra of the electrode of the electrochemical cell during the operating state biased to the first and second bias potentials. The method also includes determining a deviation in the impedance spectra at the first and second bias potentials. The method determines a degradation state of the electrode of the electrochemical cell in response to the deviation in the impedance spectra at the first and second bias potentials of the electrode of the electrochemical cell.
